Bring proven SRAM Eagle durability to your e-MTB with the GX Eagle E-MTB crank arm assembly, forged from aluminium and tuned for the loads of pedal-assist riding. This is the 165mm length — a popular middle option that suits many riders and works well with shorter-travel and mid-power e-MTB setups.

Highlights

  • 165mm crank arms, forged aluminium for e-bike durability
  • ISIS spindle interface to suit compatible e-bike motor spindles
  • Self-extracting crank bolt for easy fitting and removal
  • Accepts T-Type Eagle Transmission direct-mount chainrings (sold separately)
  • Clean black finish that integrates with the motor housing

Built for pedal assist

The GX Eagle E-MTB crank is optimised for the higher torque and constant drive of a pedal-assist system. The forged aluminium arms deliver robust, dependable power transfer ride after ride, while the dedicated e-bike fitment keeps the Q-factor in check for a natural pedalling feel.

ISIS interface and self-extracting bolt

The arms mount to a compatible ISIS spindle and use a self-extracting crank bolt, so removal and installation are straightforward without a separate crank puller. This makes motor and bottom bracket servicing far simpler.

Compatibility and fit

Designed for e-bikes running an ISIS spindle interface (SRAM/Brose and Bosch e-bike systems). Accepts SRAM T-Type Eagle Transmission direct-mount chainrings. Supplied as crank arms only — the chainring, bottom bracket and crank cap/gap cap are not included and should be selected to match your motor and drivetrain. If you are unsure which spindle or chainring your e-bike uses, contact Tune Cycles before ordering.
